value instead of text in Combobox after selection

I have a Combobox, it uses a json store sending (id,name) couples for populating value and text
when you click on the combo it shows all the right options (ie: store loads the right way)
you select an option, still everything ok, showing the selected item textwhen combobox blurs it shows selected item value, not the text!

I've run into the same problem. When you use a gridEditor with a ComboBox that has a displayField and a valueField the value field is displayed once a selection is made. I've attached a screenshot to show what it looks like. I'm sure there's a way to hack around it by catching events and going to change the raw value/display text of the grid, but it seems like this isn't the intended purpose.

Not sure if you call this a bug or not, but maybe there's something we're missing... Anyone has any ideas how to fix this?

EDIT: ... oops i didn't see that this was in the Ext-1.1 forum... i'm using 2.1, it seems from other threads the best/current method is to just create a render function for the column and build cell's rendered text from the value.
